Cosmopolitan‘s April issue features none other than Girls’ Generation‘s Hyoyeon. Collaborating with Make Up Forever —a French professional make up brand—, Cosmpolitan Korea uploaded a video to its Youtube channel in which Hyoyeon shows her technique to achieve perfect eyebrows. In the video, which can be seen here, she explains her step by step to get her characteristic eyebrow style with the help of some brushes and Make Up Forever’s Aqua Brow, a product described as “a waterproof eyebrow corrector that fills, defines and lengthens brows.” Full description of the product and shades can be found here.
